固体可燃物表面火蔓延是森林火灾、建筑火灾以及工业火灾中普遍存在的燃烧现象,是火灾研究的基础问题。对固体可燃物表面火蔓延行为进行分类,评述国内外的固体可燃物表面火蔓延行为研究现状和目前存在的主要问题。总结固体可燃物表面火蔓延试验研究的技术手段,对比分析不同因素对建立固体可燃物表面火蔓延行为理论模型的影响。这些因素包括环境流场、化学反应动力学、热解气体组分和炭化过程等。概要介绍固体可燃物表面火蔓延计算模拟的优势。最后指出固体可燃物火蔓延行为研究的发展趋势,并提出未来若干重点研究方向。
It has been held by the authors that flame spreading over combustive solids is a common burning phenomenon occurring in forest,industry and building fires,and it is a basic problem in fire science research.Flame spreading phenomena over combustive solids were classified briefly.Progress in study of flame spreading over combustive solids was reviewed.Experimental technologies of flame spreading over combustive solids were summarized.Modelling of the flame spreading phenomena was discussed with factors,such as environmental fluid,chemical dynamics and carburizing process,taken into account.Advantages of numerical simulation were introduced.Existing problems of flame spread over solid surfaces were pointed out,and prospects for the fundamental study were addressed.
